Civilians continue to be severely affected by ongoing armed conflict in Kachin and Shan states. This includes over 74,500 people who were temporarily displaced by conflict in 29 townships between January 2017 and 10 December 2018. In most cases this was short term displacement, with people returning to their places of origin within weeks or months. The UN estimates that there are now about 106,000 displaced people in camps and settlements in Kachin and northern Shan as a result of the armed conflict that resumed in 2011.

Over 32,000 people have been temporarily displaced by fighting in 33 locations since January 2018, representing more than twice the number of people over the same period in 2017. Civilians have been displaced multiple times, increasing psychological trauma, especially for elderly people and disrupting children's education. There are now almost 106,000 displaced people in 172 camps in Kachin and Shan. The United Nations has not been permitted by the Government to deliver assistance to people in need in areas beyond Government control since June 2016.

It was by far the most destructive typhoon this year. It caused over a million people displaced, damages to infrastructure and agricultural crops, thousands of houses destroyed and landslide in the highlands.
